    Looking for feedback on application of chi-square test

    I am a cost engineer working in the building construction field. I am seeking some advice/feedback on the use of a chi-square test for assessing how well a cost estimate follows an expected distribution. Our organization has developed an empirical collection of the distribution of building...

    Sample size estimation for multinomial autocorrelated data

    I'm trying to work out the minimum sample size needed to accurately characterise land cover data. The idea is to set out the a number of quadrats across the study site and identify what land cover type occurs in each. I have an idea as to how many categories there should be. So this is a...

    Multinomial probabilty

    Hi, Could anyone suggest what test should I apply in the case I have probabilities of 0. For example, I have a vector of counts 127,2,1,0 and I want to test if this vector fits one of the following probabilities (for example) p1=1,0,0,0 ; p2=0.75,0.25,0,0; p3=0.5,0.25,0.25,0 At first I...

    multinomial distribution and degrees of freedom

    Hi I have some data from a housing survey (sample size 13,500) and have found that the proportion of privately rented housing is slightly higher than the proportion of social housing. i want to test if the proportions are different. I found some advice at the link below indicating that I must...

    MLE of multinomial distribution with missing values

    Hi, I am trying to solve a problem and the results I get seem counter-intuitive. We randomly throw n balls into an area partitioned into 3 bins b_1,b_2,b_3. The size of each bins is proportional to the probability the ball will fall in it. Let's call these probabilities p_1,p_2,p_3. This...
